Zorro III speed (asynchronous vs synchrous etc..) 50mb/s ?!

[Jose]

Before you think I'm mad HEREis a review of the Cybervision54 card, wich has some busspeed tests at the end. It was the values of these tests that puzzled me. Wasn't ZIII limited to 10mb/s or something?

I seem to remember in the past, on aminet, a review of another ZIII card (don't remember wich, and couldn't find it) wich stated similar values in asynchrous mode and slower ones on synchronous (or was that the other way?..)

Anyway, can someone that knows clarify after all what are the speed etc. diferences on Sync. vs. async. modes and what more limitations are there for each mode?

I pretty remember that ZIII could do about 50mb/s on one of these modes  8-)

Yes, I was looking at the wrong results..
But it's great to know that ZIII can do much more than 10mB/s.
So does anyone know the diference between sync and async modes in performance and maye how they work and restrictions that exist in each when working with cards?

By the way, this seems to indicate poor implementation in the existing PCI to Amiga bust boards available, cause from the tests around they seem to peak at 10mb/s.

I don't have an A4000 to test it... but I recently got an A4000 motherboard on eBay for a very decent price;)

Cool avatar:-)Is that Beavis on the right side?

What about Buster rev.11 ?

So all we need is a new rev. Buster ?!!! I can't believe nonone has done it yet... there must be something more than that that comes into play.

Who want's an A4000 with Buster rev.20 with 90mB/s ZorroIII transfer?  :-D

Do you think it would be expensive to get someone to do a new proper buster chip? Or anyone left that could do it, for that matter..  :-(
